Implementation Reference

• src/toolHandler.ts:450-480 (handler)

  Primary inline handler for 'playwright_close': closes the browser instance if connected, handles errors, resets global browser state, and returns appropriate success message.
  if (name === "playwright_close") { if (browser) { try { if (browser.isConnected()) { await browser.close().catch((e) => console.error("Error closing browser:", e)); } } catch (error) { console.error("Error during browser close in handler:", error); } finally { resetBrowserState(); } return { content: [ { type: "text", text: "Browser closed successfully", }, ], isError: false, }; } return { content: [ { type: "text", text: "No browser instance to close", }, ], isError: false, }; }
• src/tools/browser/navigation.ts:61-89 (handler)

  CloseBrowserTool class with execute method implementing browser close logic (imported but execution intercepted by inline handler in toolHandler.ts).
  export class CloseBrowserTool extends BrowserToolBase { /** * Execute the close browser tool */ async execute(_args: any, context: ToolContext): Promise<ToolResponse> { if (context.browser) { try { // Check if browser is still connected if (context.browser.isConnected()) { await context.browser.close().catch((error) => { console.error("Error while closing browser:", error); }); } else { console.error("Browser already disconnected, cleaning up state"); } } catch (error) { console.error("Error during browser close operation:", error); // Continue with resetting state even if close fails } finally { // Always reset the global browser and page references resetBrowserState(); } return createSuccessResponse("Browser closed successfully"); } return createSuccessResponse("No browser instance to close"); } }
• src/tools.ts:264-272 (schema)

  Tool schema definition: name, description, and empty input schema for 'playwright_close'.
  { name: "playwright_close", description: "Close the browser and release all resources", inputSchema: { type: "object", properties: {}, required: [], }, },
